VALVEDHOUTLET EQUIPMENT FOR TANK CARS.

Application led July 1, 1922.

T 0 all whom it may concern.'

Be it known that we, THOMAS J. EN- 'rwI-sLr., HENRY P. OMAnA, andJos/EPH lV. DONNBLLY, citizens .of the United States, residing at NewOrleans, in the parish of Orleans and State of Louisiana,`have inventednew and useful Improvements in Valved-Outlet Equipments for Tank Cars,of which the following is a specification. i

The object of our present invention 1s the provision of a valved outletequipment of advantageous construction designed to be quickly and easilyinstalled in the tank bodies of tank cars and lused in conjunction withoutletlegssuch Vas at present in use, the outlet leg beingy changed inconstruction to alford Ia seat for the valve.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a vertical section illustrating our improvement as properlyembodied in a tank car body in association with an old outlet leg.

Figures 2 and 3 are horizontal sections taken in the planes indicated bythe lines 2 2 and 3 8, respectively, of Figure 1, looking downwardly.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The tank car body 1 is shown as provided with an outlet 2, and pendentfrom the bottom of the body 1 is an outlet leg 3, connected to thebottom of the body 1 by rivets 4. The said outlet leg is of the ordinarywell known construction with the exception that a valve seat 5 is groundor out in the inner portion of the upper end thereof with a View tocooperation with the valve 6 of our improved equipment.

Our novel equipment in addition to the valve 6 includes an interiorlythreaded valve casing 7, flanged at 8 to be connected to the bottom ofthe body 1 and the flange of the outlet leg 3 through the medium of therivets 4 or other connections employed in conjunction with the tank body1 and the outlet leg 8. It will also be noticed that the casing 7 isopen at its upper end Serial No. 572,271.

and .is provided in its side and lower portion with what we designedside openings 9. The valve 6 employed is preferably of the sameconstruction as the valve disclosed in our contemporary application ofeven date herewith, the said valve comprising a lower portion 10 with aconvex face 11 for cooperation with the leg seat 5, an upper portion 12,a cruciform intermediate portion formed by webs 13 which are threaded ontheir outer threads 14, and a socket 15, preferably of interior angularform to receive the correspondingly shaped lower end of a valve rod orstem 16 which is connected to the socket preferably through the mediumof a pin 17. The opposed faces of the valve portions 10 and 12 areconcave as designated by 18 to facil tate passage of .oil or othermobile substance past the valve and through the casing 7.

It will be readily apparent from the foret going that in virtue of ourimprovement the valve equipment may be expeditiously and easilyassociated with and employed in conjunction with an old outlet leg 3 andthe body 1 that carries said leg, and it will also be apparent that thevalve 6 is adaptedto be tightly closed against the seat 5 with a view topreeluding leakage, and that the valve is also adapted to be quicklyopened and closed with but little effort by turning of the rod or stein16 about its axis. Manifestly when the valve 6 is first opened 1nobilesubstance will pass from the body 1 through the upper end of the casingand also through the side openings in the casing to and `down the leg 3.It will further be noted that when the valve is opened to a considerableextent as shown in Figure 1, oil or other mobile substance will passfroin the interior of the body 1 down through the upper end of thecasing 7 past the lower portion of the valve to the outlet 3, and willalso pass freely through the side openings of the casing 7 directly tothe leg 8 so that when desired all of the contents of the body 1 may bedrained directly to and through the outlet leg 3.

In addition to the practical advantages hereinbefore ascribed' to thesubject herein, it will be noted that the said subject is possessed ofthe practical advantages ascribed to the valve and the casing disclosedin our said contemporary application of even date herewith. l

Ve have entered into a detailed description of the construction andrelative arrangement o-f the parts embraced in the present and preferredembodiment of our invention in order to impart a full, clear and exactunderstanding of the said embodiment.. We do not desire, however, to b'eunderstood as confining ourselves to the specific construction andrelative arrangement of parts inasmuch as in the future pnactioe of theinvention various changes and modifications may be made such as fallWithin the scope of our invention as defined in our appended claims.

Having described our invention, what We claim and. desire to secure 'byLetters-Patent, is l l. A valve for tank cars comprising a valve bodystructure mounted in an opening in the bottom of the tank, having anannular valve seat formed therein, and also having a threaded sleevearranged concentrically of the valve seat and of a larger diameter thansaid seat, a valve 4having a cruciform portion, t-he edges of the Websof said cruciform portion being formed for threaded cooperation with thethreaded sleeve of the body structure, and one end of said cruciformportion having a partial spherical projection extending therefrom 'andadapted to engage beyond the seat, and operating means for rotating thevalve in the sleeve for seating or unseating it, Whereby the partialspherical projection Will have universal seating cooperation With thevalve seat, and the cruciform portion extending Ibeyond the seatingportion, -directing the seating' pressure substantially in the line ofcruciform portion, the edges of the Webs of Which are formed forthreaded cooperation with the threaded sleeves of the body structure,one end of said cruciform portion having a partial spherical projectionextending therefrom adapted to engage the annular valve seat, theportion of the ualve adj acent the spherical' projection and between thecruciform web being formed With inclined stress reducing Walls fordistribut ing the application stress of the projection on the valveseat,equally through-out the cruciforrn portion of the valve, said sphericalportion being adapted for universal seating cooperation with saidiannular seat, and the threaded cooperation between the ends of the Websof said criiciform portion, beyond the circumference. of the partialspherical projection serving toapply the seating pressure in a line withthe circumference of the annular seat and the axis of the valve, andsubstantially at the seating portion of said projection, and operatingmeans `connected With the other end of the crucifo-rm portion foreffecting a rotation of the valve in the sleeve for effecting theseating or unseating thereof. v1

In testimony whereof, We afix our signatures.
